This invention relates to golf clubs, and has for its object 'the provision of an improved golf club.

We have discovered that golf clubs may be improved to a marked degree by an adherent coating of chromium upon the metallic. portion of the golf club heads. The provision of such a coating improves the driving qualities of the golf club, due to the extreme hardness of the chromium coating. Moreover,.the chromium coating is very resistant to corrosion and wear, and for that reason serves as a protective coating for the golf club'head, preventing rust and resulting'corrosion.

In accordance with our preferred form of the present invention, the golf club head has its metallic portions covered with a relatively thinlayer or film of electrodeposited chromium. In carrying out the invention, the golf club head is made in any appropriate and customary manner and may be an alloy or forged or hand-forged steel. The golf club head is then placed as a cathode in an electrolytic cell containing an appropriatechromium electrolyte, and the metallic surface of the head is covered with La layer of electrodeposited chromium of the desired thickness; In this manner the golf club head is coated with a smooth hard sur face which will ermit the making of very long drives, and which protects the head from rust and corrosion.

The golf club head is prepared for chromium plating by cleaning the surface of the parts to'be chrome-plated in any appropri ate manner as for example by a proper alkali andacid dip. The herd is then hung as a cathode in a chrome-plating bath, preferabl achromic acid bath containing asuita le catalytic agent-such as a sulphate radical, as set forth in the applications of Colin G. Fink, Serial No. 57,290, filed September 19, 1925,-and Serial'No. 76,529, filed December 19, 1925, and others of Fink and r associates. A bright, hard, lustrous,

Thus, the chrome-plat ing bath may contain other metals, such as molybdenum, which may be electrodeposited upon the golf club head simultaneously with chromium.

In practice we have successfully plated golf club heads made of an alloy, such as brass and bronze, as well as steel and ordinary iron heads with the attendant advantages of the invention. of golf clubs, such for example as the driver, have heads composed for the most part of wood with only a relatively small metallic portion. It will be understood that coating or lating of the metallic portion of such gol club heads is within the contemplation We have found it advantageous, under certain circumstances, to attach the metallic head or the metallic portion of the golf club head to the wooden club before applying the chrome plate. This is particularly ad visable in the caseof the forged steel or other iron head.

In that event it becomes necessary to protect the wood directly above the metal line during the chrome plating operation. This may be accomplished in any appropriate manner. We prefer, however, to apply a narrow band of graphite to the wood directly above the metal edge, electrodeposit cop per on this graphite band, and then immerse the club well below the metal edge. In this manner complete covering or plating of the golf head is assured.
